The experiments described in this paper were designed to isolate [3H]di-isopropyl phosphorofluoridate-binding proteins by sodium dodecyl sulphate/polyacrylamide-gel electrophoresis for the purpose of characterizing and identifying potential initiation sites for organophosphorus-compound-induced delayed neurotoxicity. The major Paraoxon-insensitive Mipafox-sensitive binding protein (Mr 160 000) was found to be identical with one previously identified as neurotoxic esterase, an enzyme that has been proposed to be the target site for organophosphorus-compound-induced delayed neurotoxicity. However, two other binding proteins with suitable binding characteristics were also found in smaller amounts, one of which has not been detected previously. Di-isopropyl phosphorofluoridate was found to phosphorylate all three of these proteins at rates similar to the rate at which neurotoxic esterase is inhibited by di-isopropyl phosphorofluoridate. Varying the concentration of di-isopropyl phosphorofluoridate or the time of incubation produced similar increases in binding to each of the labelled proteins. This suggests that the reaction rates of di-isopropyl phosphorofluoridate with proteins may be described by first-order kinetics, and the concentration of the Michael is complex formed during binding is minimal for all the phosphorylated proteins. The recovery of the binding activity in the 160 000-Mr band was found to be similar to the recovery of neurotoxic esterase activity, lending further support to the contention that this band is identical with neurotoxic esterase.

Background : Self poisoning with organophosphate pesticides is a major health problem in world wide. Organophosphorus compound poisoning is a very common toxicological emergency encountered at Mirzapur in Tangail. It is particularly common among the rural agricultural worker's which comprise a substantial group of the population of this region.Objective: The objective of this study was to find out the incidence, frequency, pattern of poisoning, outcome and aetiological aspect of Organo phosphorus poisoning patient admitted in Kumudini Women's Medical college Hospital.Methods: A total 366 cases of OPC poisoning were analysed during 1 year from January 2015 to December 2015. The emphasis was given on age, sex, socio-economic status, occupation, motive of poisoning, types of compound consumed its quality, place, distance from referral place and the ultimate outcome.Results: Young population of rural background, particularly agricultural workers were the commonest patients (51.91%). The most common motive of poisoning was with a suicidal intent, both in males (27.59%) and females (66.39%). Financial crisis was one of the most common reasons analysed as the motive behind the poisoning (54.20%). Three hundred forty four Patients recovered and 22 were expired. The major cause of death in these cases was respiratory failure followed by multi-organ failure.Conclusion : Strict of the pesticide act and involving a new policy by the government to educate the public and youth in large about the dangerous, life threatening effects of Organophosphorus compound could help amelerioating the harmful effects of such poisoning.KYAMC Journal Vol. 9, No.-3, October 2018, Page 133-135
